How to stop previously viewed/closed PDFs from reopening?

[gail5FF0]

Each time I open a PDF, Adobe is automatically reopening any PDF that I had just viewed and closed.  I closed those PDFs because I was done with them.  I don't want previously viewed PDFs to just open again on their own.

Are you asking about the paid Acrobat, or the free Reader?

Please post the exact name of the Adobe program you use so a Moderator may move this message to that forum
